Thanks guys, the tank has been running with pretty much minimal equipment. I have a sump, 25w UV sterilizer, had a Nautilus TE skimmer (upgraded to Coralife 220 after pics), have just added a clcium reactor (dosed 2-part by Natureef), just added a Phosban reactor, don't have a chiller and I live in Florida (use fans), no auto top-off (may hook one up soon). It's all pretty basic, the LR and LS are the main filters of the tank, it's not always how much money you have to spend on equipment that makes a tank.
